Автор:Richa Jackeray Год: 2011 Издание:LAP Lambert Academic Publishing Страниц: 220 ISBN: 9783844399295 This thesis is devoted towards the development of polymeric matrices and bioconjugated quantum dots for immuno-based detection of S.typhi in water. Thesis involves the surface modification of nylon membrane by grafting with GMA using free radical graft copolymerization. S.typhi specific IgG immobilized NyM-g-GMA was used as solid phase in development of ELISA for detection of S.typhi. Developed sandwich ELISA was found to be specific, reproducible, reasonably rapid and sensitive with detection limit of 103cells/mL. Developed sandwich ELISA was found to have two-fold higher limit of detection as compared to the assay performed using PS plates. For further validation of the developed immunoassay, water samples were collected from different sources in and around Delhi and tested for various parameters of validation. A method for fluorescence based detection of sandwich immunocomplex of bacteria and antibody conjugated CdSe/ZnS quantum dots on surface modified porous ...
